Firewall Rule Setup failure

As per task below I have performed the below steps:

" The Nautilus system admins team recently deployed a web UI application for their backup utility running on the Nautilus backup server in Stratos Datacenter . The application is running on port 8083 . They have firewalld installed on that server. The requirements that have come up include the following:

Open all incoming connection on 8083/tcp port. Zone should be public ."


ssh clint@stbkp01

sudo firewall-cmd --permanent --zone=public --add-port=8083/tcp


Though I got success response but still the task has been failed. Refer the screenshot.

##You must restart the firewall so that the new rules are taken into account
% sudo systemctl restart firewalld.service

Thanks. That’s correct. Its my bad
